Digital Smart Electrodes for enhanced measurements

Our Simple Benchtop Meters (HI2640 and HI2641) measure DO with the supplied Dissolved Oxygen Digital Smart Electrode (HI764080).

Advantages of our Dissolved Oxygen Digital Electrode include:

Designed for various industries and applications, this probe is durable and suitable for use in chemical analysis
Collect stable readings even in electrically noisy environments and eliminate drift with automatic noise filtering and digital processing
Built-in temperature sensor ensures optimal temperature compensation. There’s no need to manage an additional temperature probe
Change electrodes easily without recalibrating. All data from the last calibration is stored in the electrode for faster setup and less maintenance when switching electrodes
Gain traceability with auto sensor recognition and a unique serial ID number for each Digital Electrode
Equipped with a modern 3.5 mm connector that is sealed to protect against moisture and corrosion
